But safe standing has already been introduced in the United Kingdom, with Scottish champions Celtic among those who have used new rail seating in recent years.

German clubs also use pockets of the seats, which can be bolted in an upright position, in their grounds.

League One side Shrewsbury Town will introduce 500 of the seats this summer.

A government source told the BBC: "Safety of supporters is paramount. However we recognise that technology and stadium design has evolved since the all-seater policy was introduced and the time is right to look at the issue.

"The sports minister has not shut the door to fans keen on standing sections being introduced but it is important that all the evidence and viewpoints are considered extremely carefully."
